Available in PDF, EPUB and Kindle. Book excerpt: This document reports the results of a 3-part field data collection program to determine the sensitivity of user costs to pavement condition factors. Speed data were collected at 15 urban freeway pavement sites and 8 suburban arterial sites. pavement roughness and deterioration were measured at each site. Analyses were conducted to determine relationships between speed change behavior and pavement conditions. Vehicle coast-down and fuel consumption tests were conducted at 11 sites to determine relationships between total vehicle resistance force, speed and pavement conditions. Fuel consumption models wee developed and verified experimentally.

This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of this study is the extent of pavement distress impact on traffic capacity of uninterrupted road link sections. It aimed to ascertain whether road pavement distress would have significant influence on roadway capacity loss. Pavement distress is a persistence problem in Nigeria and indeed many developing countries - it is reflected in terms of increase in the followings among others: increase in travel time, and road user costs. Potholing, edge subsidence and pavement cracking under tropical climate are problematic in developing countries. Even though governments in Nigeria have spent huge sums of money to dampen the effects of poor pavement conditions, the progress made so far is painfully small. The objectives were to measure roadway capacity in the presence of pavement distress and compare with that taken without the influence pavement distress. To that effect a pavement distress impact study was carried out at 12 selected sites in Nigeria for a period of six months under daylight and dry weather conditions. Based on the circumstances prevalent at the time of survey in Nigeria the study assumed that density was a resultant of speed and flow hence not directly affected by pavement distress. This implies that roadway capacity loss was fully the result of speed changes. Vehicle types, volumes and speeds were collected at each surveyed road section and the results analysed. Capacities of the road section were estimated for three sections ('without distress', 'transition' and 'with distress') of the road link and it was found that capacities on 'without distress and 'with distress' sections differed significantly. After achieving the aim of the study, the roadway capacity loss was related to pavement distress using polynomial modelling and multiple regression techniques. Results confirm that pavement distress has relationship with roadway capacity loss and the study concludes that a significant decrease in capacity of about 30% was found and is attributable to road pavement distress.

This book was released on 2015 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the main elements of any Pavement Management System is Pavement Performance Modeling. Accurate pavement performance models can save millions of dollars through proper maintenance of the transportation pavement infrastructure. Several pavement performance models have been developed over the years to predict pavement performance. However, in the development of pavement performance models the climatic parameters were often ignored. Climatic inputs, especially rainfall, affect pavement performances because material properties change with temperature and moisture conditions particularly in ACP (Asphalt Concrete Pavement). The modulus of the unbound materials is sensitive to the variation of moisture content. Rainwater can infiltrate into the unsaturated pavement layers though cracks, joints or edges of the pavement and can deteriorate the pavement structure by reducing structural capacity. This study investigates rainfall impacts on pavement performance and maintenance costs of asphalt concrete pavement on Texas highways. Performance models are developed to accurately predict the pavement condition and performance for the Texas Department of Transportation (TXDOT) Highway pavement network for San Antonio Districts. In addition, tools are developed to accurately estimate the future maintenance cost considering rainfall. TxDOT's PMIS data for the San Antonio Texas Department of Transportation (TxDOT) District was used for pavement conditions and NOAA data was used for historical rainfall information. One Way Analysis of Variance (ANOVA) was performed to determine the significant variables for the pavement performance model. The San Antonio District's road network broken into five pavement families following functional classes such as Interstate Highways (IH) main lane, Interstate Highways (IH) frontage lane, State Highways (SH), US highways (US) and Farm to Market Road (FM). The statistical modeling reported herein shows that rainfall had a significant impact on deterioration of pavement conditions of Interstate Highways (IH) for main lanes. For Interstate Highways (IH) frontage lane and Farm to Market (FM) pavement families combination of rainfall and traffic class had significant impact on the pavement performance model. Engineering knowledge supported the concept that increasing amount of rainfall will degrade the pavement structure at a faster rate. However, statistical analysis of the available data showed that rainfall did not have a significant statistical impact on the performance model of State Highway (SH) and US highways (US) pavement families. Other significant factors that affect the flexible pavement performance identified in this research for all pavement types are pavement age and previous year's distress scores. Previous maintenance and rehabilitation (M&R) activities performed on a pavement section will also have a significant impact on the pavement deterioration model for pavement families except for Interstate Highway (IH) main lanes and U.S Highways (US). In this research, an application was developed to estimate the maintenance cost of the network considering the rainfall and other significant factors. This tool will allow users to accurately predict future maintenance costs and allocate appropriate budgets.

This book was released on 1999 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to transportation agency planners; design, construction, and maintenance engineers; and administrators, managers, economists, and other decisionmakers involved in programming highway pavement projects. This synthesis describes current practice with regard to road user and mitigation costs in highway pavement projects. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search of both domestic and foreign publications. This report of the Transportation Research Board provides detailed information on the various methods employed by transportation agencies to estimate user costs. The advantages and disadvantages of each are reported. Information on the various components of user costs (that is, time related, vehicle operating, safety, and environmental costs) is also included. In addition, the study reports on the various mitigation strategies available to agencies to reduce user costs. Information is also provided on how user costs and mitigation strategies have been applied to evaluate different alternatives; and how uncertainties, political considerations, and quality control contribute to the decisionmaking process.
